干掉CH340N？不错，这功能应该不难实现。
总是觉得现在的CH340N价格仍然有点高。 ...
是的，刚花几块钱买了俩ch340

到时生产时顺便把USB转串口的程序写进去，让用户直接用，岂不更直接和方便。哈哈

8 pins is too limited, 10pins (same size footprint) is a more common small USB solution size.
Some even offer 0,5mm MSOP10.
On the Sw side, the STC example codes need to improve a lot, to compete with the Ch340/Ch343 but that is a very good target - open USB-UART that works properly

yes，8pin with USB only five io is too limited，sop16 is OK。
